Just ran across this. It's an in-depth video lecture by Professor Marina Picciotto on the affects of nicotine and the bain and behavior. Some of it way over my head - she earned her Ph.D. in Molecular Neurobiology at The Rockefeller University in New York City. But some of what she says is oh so easy to grasp. I've only watched the first half hour so far, but at the 15 minute mark is where lightbulbs started going off in my head. Dr. Hurt's video on here Nicotine and your Brain is the easy lesson for beginners. Dr. Picciotto's video is for those Master Students here who want to really learn in greater depth why we're addicted to nicotine. It's very heady and fascinating.
